SPECIFICATION formingpart of Letters Patent No. 295,272, dated March 18,1884.

Application filed October 30,1833. (No model.)

To @255 whom it may concern.-

Be it known that 1, Max MosLER, a citizen of the United States, residingat Cincinnati,

county of Hamilton, State of Ohio, have invented certain new and usefulImprovements in Fire-ProofSafes, of. which the following is aspecification.

The object of my invention is afire-proofsafe which will afford absoluteprotection in case of fire, and yet be lighter to handle and cheaper toconstruct than the ordinary tire-proof safe. Its object is also toprotectthe contents from dampness or in} ury from the moisture of thefireproof filling when closed for a long time.

With these objects in view, my invention consists in entirely inclosingthe inside of the safe when closed by an air-chamber, which is entirelyout off from the exterior air when the safe is closed, but has freecommunication with the external air when the safe-door is open.

It consists, also, in certain peculiar arrangements of the inside of thedoor and bolt-work, all of which will be fully described in connectionwith the accompanying drawings,and then particularly pointed out in theclaims.

Figure 1 is a central vertical section of my improved safe, taken fromfront to rear of the safe, and looking to the hinge side the door isshown open and in inside plan view, with part of the inside covering-plate removed to expose the bolt-work and means of fastening the plate.Fig. 2 is a horizontal transverse view taken centrally through theclosed safe. Fig. 3' is an inside plan view of the form of door andbolt-work I use in constructing double-door safes. In this view the backplate is removed. Figs. 4 and 5 are details showing the manner oflocking the back plate to the inner side of the door.

The exterior or frame-work A of the safe is constructed in the usualmanner, as is also the door-frame B, except the inner flange throughwhich the bolts pass. The bolt-holes in this inner flange pass entirelythrough, to comma nicate with the air-chamber O, which entirelysurrounds the body of the inside box. D. This box is secured on theinside flange of the doorframe in the usual manner, and the air-chamher0 is formed by a larger box, E, which is secured upon one of theintermediate flanges of the door-frame B.

The bolts F F, instead of being solid, as customarily employed, aretubular, to open communication between the chamber in theinside of thedoor and the chamber O,surrounding the recep tacleDnvhen the doorisclosed. The bolts F, Fig. l, are for this purpose open at theirinnerends, while the bolts F are longitudinally slotted at f for the samepurpose. The space between the box E and the outer walls of the safe isfilled with a nonconducting fire-proof material. The inner flange of thedoor in the single-door safe, Fig. l, is beveled off at the pass thebolts F,which radiate from the center of the door. The angles oftheframe B are also beveled to correspond with the bevel on the innorflange of the door. The beveled corners of the frame are perforated toreceive the bolts, which thus communicate with the air-chamber 0 whenthe safe is closed. The bolts are shot out from the centerof the doorand retracted by a slotted cam-disk, G, acting upon pins which projectfrom the coupling-pieces f into the slots. The cam G is secured upon thebolt-arbor which passes through the door, and is provided with the usualhandle or knob upon the outside. The coupling-pieoefisaringslipped overthe end of the tubular bolt F and held to it by a setscrew and an armprojecting from one sideof the ring, and having an outwardlyturned endor pin to enter the eccentric slot in the cam-disk G. I prefer to usethis separate upon the bolt for the purpose of regulating its throw; butthe end of the tubular bolt could be cut away to leave an arm or spurupon the innor end, in which the pin which enters the eccentric slot indisk G could be secured, and thus dispense with the coupling f. Thebolts F are guided radially,when the disk G is turned,by theperforations in the flange of the door and door, which forms the innerwall of the airchamber in the door,which chamber also contains the lockand bolt-work of the safe. The inner plate, H,(shown broken awayin Fig.1,) is preferably hinged to the flange on the hinge edge of the door. Tothe inside of the plate H I secure one or more Z-shaped angle-pieces, hwhich, when the cam G is turned to protrude the bolts,as seen in Fig. 1,will lock the door or plate H against opening. The purpose of thisarrangement is to prevent any one from in corners, and the beveledportion perforated toguide -lu gs f secured upon thelock-plateofthecouplingpiece because it admits ofadjustment specting the lock notshown) which dogs the bolt-worl ,and learningits combination. \Vhen thebolts are retracteoLthe cam G, in retracting them,passes from over theinwardly-prey ecting arm of the piece h, and the door H may then beopened, so that when it is desired to leave the safe-door open for sometime it is only necessary to throw the bolt-work as when the safe islocked, and by turning the lock-arbor disarrange the combination of thetumblers. Thus the door H can only be opened by those knowing thecombination ofthe lock. The same result will be accomplished in the doorhaving the common form of bolt-work as seen in Fig. 3 by having thebutton or lug h on the front edge of the inside plate or door to passbetween the edge of the inside flange and the bolt-bar f so that thebolt-bar will engage its hooked end when the bolts are thrown out.

For the purpose of allowing the button to pass inward, the bolt bar isnotched, as shown, which notch should be a little larger than theinwardly-projecting end of the fastening piece or button I is in width.

It is obvious that the button h or a similar device secured upon theinside of the plate H could be engaged by pins or spurs upon the bolts,so as to be protected against opening by the combination-lock. Itherefore do not limit myself to the exact devices shown.

I'prefer to make my safe with a removable bottom plate,so that theouterchamberbetween the walls of the safe and box E may be filled fromthe bottom with fire-proof material; but it may also be filled from theback, as safes are now usually filled.

I am aware that it is not new to arrange the solid bolts of a safe-doorradially, so that they may be projected simultaneously from the corncrsof the door by means of devices located at the center thereof; and I amalso aware that it is not new to bevel the corners of the door anddoor-frame of a safe, and I wish it understood that I do not cl aimeither ot'these features per se.

\Vhat I claim as new, and desire to secure by Letters Patent, is

l. The combination, in a fireproof safe, of air-chamber G, surroundingthe inner receptacle, D, and the safe-door, having an inner airchamber,which is also the receptacle for the bolt-work, with tubular bolts tocommunicate with the chamber 0 and the chamber in the door when the safeis closed.

2. The combination, in a fire-proof safe, of the safe-body A and steppeddoor and door frame with the inner receptacle, D. secured upon the innerflange or step of the door-frame, and the box E upon one of itsintermediate steps-0r flanges, so as to form two chambers within thesafe-body, the outer one for the reception of a tire-proof filling,andthe inner one bci ngan air-chamber,substantiall y asspecitied.

3. The combination, with a safe having an air-chamber, and a door-framethe corners of the inner step of which are beveled and perforatedopposite said air-space. of the door provided with an air-chamber, andhavingits inner step similarly beveled and perforated, the tubular boltsradiating from the center of the door, and adapted to be projectedthrough the beveled corners ofthe door and door-frame, and means forsimultaneously projecting and retracting the bolts.

4. The combinatiomwith the safe-door having a chamber, and the bolt-workarranged within said chamber,ofthe inner door or plate, constructed toclose said chamber,and provided with lugs adapted to be engaged b y theboltwork when the bolts are shot.
